Ghost Fragment: Vex 2 is a Grimoire card from the original Destiny (Destiny 1), found under Enemies → Vex. Grimoire cards held most of the game's lore and were read on Bungie.net and in the companion app, not in the game itself.
Card text
SUNDARESH: So that's the situation as we know it.
ESI: To the best of my understanding.
SHIM: Well I'll be a [profane] [profanity]. This is extremely [profane]. That thing has us over a barrel.
SUNDARESH: Yeah. We're in a difficult position.
DUANE-MCNIADH: I don't understand. So it's simulating us? It made virtual copies of us? How does that give it power?
ESI: It controls the simulation. It can hurt our simulated selves. We wouldn't feel that pain, but rationally speaking, we have to treat an identical copy's agony as identical to our own.
SUNDARESH: It's god in there. It can simulate our torment. Forever. If we don't let it go, it'll put us through hell.
DUANE-MCNIADH: We have no causal connection to the mind state of those sims. They aren't us. Just copies. We have no obligation to them.
ESI: You can't seriously - your OWN SELF -
SHIM: [profane] idiot. Think. Think. If it can run one simulation, maybe it can run more than one. And there will only ever be one reality. Play the odds.
DUANE-MCNIADH: Oh...uh oh.
SHIM: Odds are that we aren't our own originals. Odds are that we exist in one of the Vex simulations right now.
ESI: I didn't think of that.
SUNDARESH: [indistinct percussive sound]
